Research Abstract |
The material under test of this study has dealt with extensive green roof systems, typically made by drainage boards, artificial light-weight soil and turf. The least peak runoff 0. 298L/min obtained when the only drainage board was installed. The number of runoff coefficient was 0. 63. The least peak runoff 0. 093L/min obtained when the extensive green roof system with sod was installed. The number of runoff coefficient was 0. 30. Using these values, we simulated Tokai torrential rain (2000), and calculated the water runoff from some case study areas. As the results, we suggested the characteristics of green roof installed area, especially reduction of the storm water runoff.
